Reversible logic has attracted significance attention in recent years, leading to different approaches such as synthesis, optimization, simulation and verification. In this paper, we propose the design and optimization of n-bit reversible binary comparator. The circuit for MSB and one-bit comparator cell using NOT, PG and CNOT gates are designed. The n-bit(More)
Scan chain structure consumes 10%~30% of die area, and most yield loss is caused by scan chain faults. This makes scan chain diagnosis be the key important method to ensure the high-quality products. The conventional scan chain diagnosis techniques usually conduct to a large range of suspect faulty flip flops. The failure analysis of those suspect faulty(More)
